PerranOak:
Often, when I am soldering onto a Vero board, the insulation on the connecting wire gets so hot that it melts back and recedes up the core!

This means that a short is highly likely.

Is there any connecting wire that can stand the heat?

Cheers.

If the insulation is catching fire, then the soldering iron is too hot. You should invest in a temperature controlled iron.

Silicone and PTFE insulation are strong enough to withstand the heat, but they're much more expensive than PVC.

Whatever wire you use, tin it before you solder to the board, that way the insulation can be flush with the board, even if it receded during tinning.

For bridge wire between pads, pre-tin (as mentioned) but you could strip more wire than needed and use an aligator clip to draw away heat, then clip when done. If the iron's too old/powerful, use a variac if you have one. YMMV

The alligator clip might be a good tip. It's amazing how effective adding even a relatively small amount of mass can be as a heat sink.

Thanks all.

I have a Hakko FX-888D set to 325 Centigrade - is this too hot? I get advice of anything between 300 and 350 so I went for the middle!

Cheers for tips.
